-36. (canceled)
A method of manufacturing a collection of matter bound by a polymeric binder comprising:
- (i) providing a collection of matter;
- (ii) providing a water-soluble pre-reacted binder composition in the form of an aqueous solution or dispersion, the aqueous solution or dispersion containing no more than 80 wt.-% of said pre-reacted binder composition, and the pre-reacted binder composition comprising the reaction product(s) of
- (a) at least one carbohydrate component selected from the group consisting of dextrose, glucose, fructose and mixtures thereof, and
- (b) hexamethylenediamine,
- wherein the pre-reacted binder composition comprises at least one pre-polymer having a molecular weight in the range of 1 to 500 kDa in an amount of 2 wt.-% or more, based on the total weight of the pre-reacted binder composition;
- (iii) applying the aqueous solution or dispersion to the collection of matter;
- and
- (iv) applying energy to the collection of matter containing said aqueous solution or dispersion to cure the binder composition.
A method of manufacturing a collection of matter bound by a polymeric binder comprising:
- (i) providing a collection of matter,
- (ii) providing a water-soluble pre-reacted binder composition in the form of a first aqueous solution or dispersion having a shelf life suitable for storage, the pre-reacted binder composition comprising the reaction product(s) of
- (a) at least one carbohydrate component selected from the group consisting of dextrose, glucose, fructose and mixtures thereof, and
- (b) hexamethylenediamine;
- (iii) subsequent to handling of the first aqueous solution or dispersion selected from storage and transportation, adding hexamethylenediamine to the first aqueous solution or dispersion to obtain a second aqueous solution or dispersion,
- (iv) applying the second aqueous solution or dispersion to the collection of matter, and
- (v) applying energy to the collection of matter containing said second aqueous solution or dispersion to cure the binder composition.
